What is the principle of Rubik's cube?

In fact, it is to "match" and "align" the edges and corners according to the color of each central block.

The Rubik's Cube has 6 colors and 6 sides. The internationally accepted colors are: white for the bottom D, yellow for the top U, blue for the front F, green for the back B, orange for the left L, and red for the right R. The Rubik's Cube is divided into six central blocks (middle blocks on each side), eight corner blocks and 12 side blocks. The center block is a fixed structure, and the corner block and the side block are rotated to restore the Rubik's cube.

magic formula

1, up, right, down, right, anti-left-right-swap the positions of the small squares on the two adjacent vertices above.

2. Up, Left, Down and Down-Swap the positions of the small squares on the top two diagonal vertices.

3. Top left, bottom left, top left, bottom Zuo Zuo and bottom Zuo Zuo-the small squares on the top three vertices are rotated by 120 degrees.

4. Up, left, left, left, right, down, right, down, right-exchange the small squares in the middle of the three sides in turn, while ensuring that all other small squares do not move.

All formulas can ensure that the position and angle of the small box below remain unchanged. You can first face the side of the Rubik's cube as the bottom. Then:

1, adjust the positions of the four small squares on the top vertex with formulas 1 and 2.

2. Adjust the angles of the four small squares on the top vertex with Formula 3.

3. Adjust other small squares on the edge with Formula 4.
